Is there a silicone strip with a diameter of 70? According to the name of the installation part (component), it includes: engine cover sealing strip (HOOD), which can be divided into front, side and rear; door frame sealing strip (DOORSEAL); front and rear Window sealing strip (WINDOWSCREEN); side window sealing strip (SIDEWINDOWSEALING); sunroof sealing strip (SUNROOFSEALING); door first road sealing strip (PRIMARYDOORSEAL); window guide groove sealing strip (GLASSRUNCHANNEL); inside and outside strips (water cut) (WAISTLINE) ; Trunk seal (TRUNKSEAL); anti-noise seal (ANTI-NOISE); dust-proof strip (ANTI-DUST), etc. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. Is there a silicone strip with a diameter of 70? It is formed by microwave vulcanization process at one time, with a smooth and beautiful surface, no joints, good elasticity and resistance to compression deformation, excellent aging resistance, excellent flame retardancy, low smoke and low toxicity; stable product performance , High dimensional accuracy, six, burning, PVC sealing strips will foam, shrink and emit black pungent smoke when burning, insufficient combustion, leaving hard plastic residues, silicone rubber sealing strips are almost smokeless, odorless, and burning Fully, the burned substance will become a white powder. In addition, the material proportion of this type of product (above 1, 4) is comparable to that of PVC (low-end vulcanized EPDM rubber strips have a larger proportion). The window rate is similar to that of PVC rubber strips, and the cost of use is relatively high, which is difficult for door and window companies to accept , The sealing strip can be classified according to several methods such as section shape, vulcanization method, use part and purpose, use material, etc. Product characteristics 1) Light bulk density, strong expansion and contraction strength, non-absorbent (replace the traditional three oil four felt, asphalt wood fir Board and other materials). It is used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in fact its maintenance is very It’s important because once it’s aging and damaged, it will cause rain leaks in the cabin and increase the wind noise of the car. Rain leaks can easily corrode the body. We can keep the car sheltered from wind, rain, dust and heat by maintaining it. , The effect of sound insulation, and when the body is shaken and twisted, it also plays a role in buffering, absorbing shock and retaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must maintain it frequently. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety.

Ensure personal safety. Is there a silicone strip with a diameter of 70? For car sealing strips, we must pay more attention to maintenance and master the correct maintenance method, otherwise the maintenance effect will not be achieved. Let us understand the importance of car sealing strip maintenance. Well, the characteristics of the product. The elasticity and compression resistance of the car sealing strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product very strong and durable during use , And it is very convenient to install. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass. 3) It has an independent open-cell bubble structure. The appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion The shrinkage changes and changes to enhance the sealing, expansion, and water stop effect of the joint. Doors and windows are the barriers to the quiet living environment. Doors and windows are also important and interesting bridges between people's internal world and the external world. The sealing performance of doors and windows is constantly enriched, and the opening is more and more catering to the needs of life. This significant change It implies the improvement of the quality of life. In fact, they all represent a trend of living quality. When doors and windows form concepts in the process of human civilization, doors and windows have also become another carrier of human civilization, and they can be used to satisfy the use of functions. Transformed into a desire for spiritual refuge and ideal extension. Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, processing aids, and accelerators. 2. The automobile product rubber of claim 1, wherein the automobile product rubber is based on a weight ratio of 100 for EPDM, 90 for carbon black, 20 for softening oil, and 15 for processing aids. , The accelerator is 5.
